Note: I have two different use cases. One is a DEFSYSTEM -level :DEPENDS-on ((FEATURE :SBCL :SB-THREAD)) or similar to indicate what *FEATURES* the system assumes, so that tools like Quicklisp could use this information to good effect. It should be checked during attempts to OPERATE LOAD-OP on system, with an error if the feature is not present, and it should be available through system introspection. The thing that I'm currently using :IF-COMPONENT-DEP-FAILS :TRY-NEXT for currently is (:FILE "sbcl" :IN-ORDER-TO ((COMPILE-OP (FEATURE :SBCL)))) which is quite different.
